To all lwhom it may concern;

Be it known that l, JACOB H. GENTER, a

of Newburgh, in the county of Orange and State of New York, have 'invented a new and Improved Projecting Apparatus, of which thefollowing is a full, clear, and exact dea new and improved projecting apparatus more especially designed for use as. an ad vertising medium, `and arranged to display the images oi" desired advertising matter on a screen, wall, sidewalk or other surface together with a revolving image having di'erently-colored vsections to form an attractive feature of .the display.`

ln order to accomplish theV desired result, use is made of a periodically-rotated carrierprovided with slides adapted to move successively into the iield of the projecting apparatus, each slide being provided with advertising matter and with a blank space,

and a rotating disk slide also' extending inv the field of the projecting apparatus and arranged in juxtaposition relative to the said blank space and carrier slide. A practical embodiment of is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional sidev elevation of the projecting 4apparatus ori the line4 1--1 of Fig. 2; Fig. -2 1s a sectional side elevation of the same on the line 2--2 of Fig. 1; Fig.

3 is a sectional side elevation ofthe same on of the rotating disk slide andthe mechanism.

for rotating the same; Fig. 5 isan enlarged sectional side elevation of the same on the line 5-5 of Fig. 4f; Fig. 6 is a face View of one of the carrier slides; Fig. 7v isa tace view of the circuit breaker; and Fig. 8 is a side elevation of a modified form of the motor and the mechanism fior intermittently rotatin the. slide carrier, part of which is shown 1n section'.

lin the casin A et the projecting apparatus is mounts an objective B, a condenser lens C and a source of light D located in the rear of the condenser lens C, as indicated in Figs. l and 2. rlhe casing A is having a rod E passing through an aperthe invention tured boss A held on the bottom of the casing A. Theboss A is provided with a set screw .E2 adapted to engage the rod E so as to securely fasten-'the casing A on the rod E of the bracket'E.

Within the rear portion of the casing A 1s nl ountedto rotate lintermittently a slide carrler F, preferably in the form of a skele-l .fton wheel, provided at its peripheral face with' guideways F for the reception ofre- .movable slides G containing subject matter G' to. be projected and a central blank vspace G 2, as indicated in Fig. 6. By reference to Figs. 1 and 2 it will be noticed that t e icondenser lens (l and. the source of light 'D are arrangedy within the slide carrier F in such ja manner that theV slidesG move successively into the iield of the projecting zapparatus, vthat is, between the condenser lens C and the objective'B. Y. The slide carrier F- is rotated vtently and for this purpose the following .arrangement is made: The hub F2 'of the slide. carrier F is mounted to .rotate loosely Aon astud yH attached to a door or cover A2 on oneside of the casing A, and on the said hub'F 2 issecured a gear wheel I forming Apart of a\train of gear wheels I driven by` a Vsuitable motor I2, such asY the usual spring motors usedin clocks and the like.

J2 `drawn in an upward direction by a spring d'4. The arm J2 forms anjarmature lever for a pair of electro-magnets K, to swing the arm J3 downward at the time the "electro-magnets K are energized, and when the electro-magnetsfK are denergid the arm 1 J3 swings `u ward by the action of its spring J4. N orma ly the escapement lever J locks the escapement wheel J against movement so that the slide carrier F is at a standstill, but whenA a swinging motion is given to the escapement lever J by the action of the electro-magnets Aand the spring K2, as above described, then the motor l2 rotates the slide carrier "F a distance suiiicient to move the next following slide G into the field of the projectingapparatus.

The electro-magnets K are in an electric 'circuit K provided with a battery or other source or electrical energy K2, and the elecintermit- 0n the hub F2- The casing of the motorl2 is mountedon a ksuittric circuit K 'is provided with a circuitV breaker L controlled by a motor N similar to the motor L2 and removably attachedto the casing A by a set screw N (see Figs. 1 and 3). rlhe driven arbor N2 of the motor N is provided with an arm Lvadapted t0 move in contact with spaced- Vcontacts L2 arranged on a ring L3, to which oneterminal of the electric circuit K is attached, as plainly indicated in Fig. 7. The other terminal of the electric circuit K is attached to an insulated arm L4 in engagement with the hub L'i on the arm L. It will 4be Jnoticed that when the motor N is running the arm- L moves into and out of engagement with i the circuitK is closed so that the electromagnets K are energized `to contact with the arm J2 of the escapement lever J. When the arm L moves out of engagement with the contact L2, the circuit is broken and the arm J2 is returned to uppermost position by the action of its spring J 4, as previously explained. The number of contacts .4 L2 correspond to the number of slides G arranged on the slide carrierF, and the esv capement'wheel J is*V provided with double the number of teeth of thenumber of slides G, so that at each action of theescapemen't lever d the slide carrier F isturnedto move the neXt following slide G intolthe field of the pro3ect1ng apparatus.

ln front of the slide G in active position at the time is arranged a disk slideO, of glass, mica or other` suitable transparent material, provided with differently-colored sections O', as plainly indicated in Fig. 4. rlhe disk slide 0 is at the time in the field of the projecting apparatus andin register with the blank space G2 of the lslide Gr,.

' so that when the apparatus is in use the image of the advertising matter 'G' is projected onto a distant surface together with the colored images of the sectiofnsv O of the disk 0. Now in order to enhance the appearance of this colored imagel the disk O is continually rotated, and for this purpose the disk is driven from the motor N. The disk 0 is mounted in a ring .O2 mounted to rotate in an annular bearing P on va frame P attachedv to the housing of the motor N. rlhe peripheral face of the ring @2 is provided with a gear wheel 03 in that by the arrangement described the mo torN is used for rotating the disk slide O -and for actuating the circuit breaker L conltrolling the electro-magnets K and the escapement lever J to intermittently rotate the slide carrier F;

lThe condenser lens Clis mounted in a frame C held on a rod C2 adjustably secured'by a setscrew Cton a bracket A attached to the side A2 of the casing A opposite the door A2, and the source of light l) is mounted on a bracket A2 likewise attached'to the side A6. By mounting the slide carrier F, the motor l2 and the escapement mechanism on the door A2 the said parts can be readily removed from the cas,

ing for change of slides, repairs or other purposes on simply removing the door or cover A2'. Ashield A2 is arranged in the casing 'A intermediate the peripheral face of the slide carrier F and the motor N to protect the latter against the heat emanat use may be made of a mechanically-con trolled escapement, such, for instance, as

shown in Fig. 8. 'ln this case an escapey ment wheel R is secured on the hub'F2 of the slide carrier F, and the teeth R of this escapement wheel R`are adapted lto be successively engaged and released by an escapement lever R2 fulcrumed at R3 on the bracket A2 of the casing cover A2, and the said escapement lever R2 is drawn by a spring R4 to normally hold the escapement lever in engagement with one of the teeth R of the escapement wheel R. VThe escapement lever R2 is provided with anextension arm R5 adapted to be engaged by a pin S held on the face of a gear wheel S forming part of a train of gear wheels driven from a spring motor S2, the train of gear .wheels also driving a governor wheel S2 to insure uniform rotation of the train of gear wheels.

@n the hub F2 of the slide carrier F is secured a pinion T in mesh with a gear Wheel T forming-part of a train of gear Wheels driven by a motor T2, preferably of the spring type, the same as the motor S2.

By the'arrangement described the slide car- 'rier F isv rotated from the motor T2 Whenl.
